Greenstick fractures mostly occur in children and rarely in adults. In adult zygomaticomaxillary complex fractures, the greenstick fracture at the root of the zygomatic arch is occasionally encountered. This makes it difficult to move the fracture segment. Therefore, achieving anatomic reduction is very difficult. Our preoperative 3D repaired model shows that if only the maxilla and zygomatic bones are restored, the patient's face will still have depression and protrusion. The greenstick fracture segment at the root of the zygomatic arch needs to undergo osteotomy to achieve anatomic reduction and restore facial symmetry. The patient's facial appearance was restored after the surgery. The postoperative computed tomography scan showed good alignment of the fracture. The authors believe that a fracture at the root of the zygomatic arch can serve as an indication for open reduction and fixation.
青枝骨折多发生于儿童，成人罕见。在成人颧上颌复合体骨折中，偶尔会遇到颧弓根部的青枝骨折。这使得骨折段难以移动。因此，实现解剖复位非常困难。我们术前的三维修复模型显示，如果仅恢复上颌骨和颧骨，患者面部仍会有凹陷和突出。颧弓根部的青枝骨折段需要进行截骨术以实现解剖复位并恢复面部对称性。术后患者面部外观得以恢复。术后计算机断层扫描显示骨折对位良好。作者认为，颧弓根部骨折可作为切开复位内固定的指征。
